The project focuses on the development of an electronic fuel injection system for a single cylinder small engine. The engine currently used a carburettor fuelling system which is less efficient in fuelling control thus resulting in high fuel consumption, lower engine performances that contribute to poor emission released to the environment. The main idea of the project is to develop an electronic fuel injection control system on the current single cylinder engine to improve the engine operating region of efficiency and hence produces a better engine performance. In addition, the electronic fuel injection system should be capable of producing a better fuel controls thus resulting improved emission. The project implementation includes the design, simulation and construction of prototype electronic fuel injection system. The project includes quite a substantial literature studies, software modelling and simulations, and hardware on-board of actual prototyping. The project deliverable in the form of hardware prototyping consisting of an engine control unit, sensors and actuators and actual data collected from the electronic fuel injection systems. This study shows that it is viable to use simulations and modelling approach in designing and analyzing an electronic fuel injection system. Experiment conducted using potentiometer as sensors input and to represent engine load and utilizing the results from the modelling and simulations. It is indicate a potential in achieving good performance in term of fuel delivery compared to carburettor fuelling system.
